Abstract
OBJECTIVE. This study was performed to determine whether noninvasive imaging with CT angiography and MR angiography in the preoperative investigation of living, related kidney donors provides sufficient information for the surgeon.MATERIALS AND METHODS. Eighty consecutive potential living kidney donors were investigated. Fifty patients underwent CT angiography and 30 underwent MR angiography before donor nephrectomy. CT was performed using 3-mm collimation with a pitch of 1.6 after the injection of 150 mL of nonionic contrast medium. The axial data, multiplanar reconstructions, and maximum intensity projections were reviewed. MR angiography was performed on a 1-T magnet using a contrast-enhanced three-dimensional gradient echo technique. Maximum intensity projections and axial reformations were reviewed. Imaging findings were compared with the surgical results in 54 patients.RESULTS. CT angiography and MR angiography were 100% sensitive in identifying the main renal arteries and renal veins.
